Offset (R3OFFSET)

Command: R3OFFSET

Offsets lines, arcs, polylines, polyline segments, and circles. Unlike AutoCAD's built-in OFFSET, R3OFFSET lets you enter the offset distance in any unit regardless of the drawing units — useful when working from field notes in a different unit system.

Usage

  1. Type R3OFFSET or click Offset in the ribbon
  2. Select the object to offset
  3. Enter the offset distance in your chosen units
  4. Click to specify which side to offset to

Offsetting a polyline segment

Hold Ctrl while picking a polyline to select a single segment rather than the whole polyline. The selected segment is offset as a separate line or arc.

Supported entity types

Unit options

The offset distance is entered in the current input units (set in R3UNITS). You can switch units inline by typing a keyword at the distance prompt — the same keywords as in R3TRAV:

Type Switches to
m Metres
f Feet and inches
e Decimal feet
u US survey feet
l Links

Notes

  • The offset distance is always converted to drawing units internally — the drawing unit scale is respected
  • The result is a new entity on the same layer as the source entity
